CONSTRUCTION FOR TAKING POWER FROM AUTOMOBILES.

Specification of Letters Patent.

Application filed January 25, 1911. Serial No. 604,543. I

To all whom it ma concern:

Be it known t at I, RALPH L. MORGAN, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Construction for Taking Power from Automobiles, of which the following is a specification.

The object of this invention is to provide a new and improved means for taking power from an automobile.

It has been found desirable to provide means whereby power can be taken from automobiles, particularly trucks, for various purposes, such as operating a crane to load or unload the automobile; for pulling the truck out of holes; power to other machines.

The particular object of the present invention is to provide a simple arrangement whereby this purpose may be accomplished and also to improve the rearaxle construc tion of automobiles.

To this end the invention consists in taking power from the back or rear axle of the automobile, by providing the driving shaft or live axle which extendsfrom and is taken therefrom while bevel pinion B on driven by the differential, with meanssuch as a capstan or pulley for taking power therefrom, and in making the clutch mechanism which connects said live axle to the driving wheel disengageable from said wheel without disengaging said shaft'from the differential, so that by disengaging said driving shaft from the automobile wheel, said driving shaft may be driven and power the automobile remains stationary.

The invention also consists of certain improved arrangements of parts hereinafter more particularly described. Enough of an improved back axle construction is shown in the accompanying drawing to illustrate the application of my invention.

Referringto said drawing and in-detail, Figure 1 is a sectional plan view of a back axle construction with my improvementsi applied thereto. Fig. 2 is a partial end ole; vation of the disengageable clutch herein? after described, .and Fig. 3 view of the brake mechanism. A g 4 Referring to the drawing and in detail, A designates part of a back .axle' casin driven from the motor, which shaft has fa or for supplying a. shaft which 1s be applied to either or both driving shafts its end, which 'pinion meshes with and drives a bevel gear C which carries the usual differential D.

E-E designate the driving shafts or live axles, the inner ends of which are squared and fit into square holes in the differential. These parts are of any ordinary or ap'- proved construction.

W designates one of the automobile wheels which is journaled to revolve on the end of a tube 25 driven into the casing A. By journaling the wheels 7 on the ends of these tubes 25 a very strong construction is provided. Only one of the rear wheel constructions is shown, as this construction is duplicated in connection with the other rear wheel if it is desired to arrange the parts so that power can be taken from either or both sides of the automobile. The construction used in connection with the wheel illustrated will now be described.

is a driving a square hole to engage the square end of the seated in a hub formed in l hub.

driving shaft. This driving pulley or capstan F is held in place on the end of the driving shaft by a nut 10 threaded thereon. The

driving pulley or capstan F is provided with an extending clutch 11, as shown more particularly in Fig. 2, said clutch being shapedto engage tightly with the spokesof the wheel so that when the parts are in the position shown in full lines in Fig. 1, said driving shaft or live axle will be connected to said wheel W. This construction is used with heavy automobile trucks where the wheels are made of steel castings. In lighter automobiles, the clutch is usually arranged to engage a clutch formed on the hub of the wheel, as well understood.

The automobile wheel W is provided with a brake rim 12, fitting in which is a brake1 3 which 'is operated by a brake cam 14 connectedto the usual brake lever. The

grooves.15-15 engaging which is a ball 16 normally pressed inward by ,a spring 17 the pulley or capstan'F, said spring being held in place is a partial.;- .by'a screw 18 threaded into the end of said By this arrangement, the driving shaft can be held in its inner or outer position.

The construction previously described can or live axles. If applied to both liveaxles,

be locked from rotation if desired.

The operation is as follows:--With the parts in the position shown in full lines in the drawings, the axles are connected to the automobile wheels so that the automobile the difierential 7 wheel. lt'is desirable to ''to use the locking device can be driven as usual. When it is desired to take power from the automobile, the auto-- mobile is stopped and the brakes set. 'lhen the capstan or pulley is pulled outwardly to the position shown in dotted lines Fig. 1. When in this outerposition, the ,clutch 11 will be disengaged from the spokes of the wheel but the drivin shaft will p 6 be disengaged from the di erential, where when is driven from the 'automo-' bile engine the capstan orpulley 18 will be rotated and no power will be applied to the automobile wheels. 7 If the duplicate construction previously described-fie employed, and power taken rom' ay one live axle,

the other live tale is preferably blocked from rotating by'means of one of the screws 20 and lock nuts-21, said screws being set inwardly to engage the 'slabbed portion of the driving shaft it is desired to render inoperative. It is not necessary to use this look, as of course, the difierential is inoperative to drive the automobile when one driving shaft or live axle is disengaged from its set the brakes while take place to prethe operations described automobile. Addivent any creeping of the tionally, if a. great-deal of power is to be transmitted or work is to be done, itis better on the live axle which is not to transmit power, which will cause the device to run more easily and with less vibration.

The details and arrangements herein shown and described-may be "greatly varied by a skilled mechanic without departing from. the scope of my invention'as expressed in the claims.
